Katy Perry, Steven Tyler and Maroon 5 are among hundreds of music industry figures accusing You Tube, Google and other tech companies of ignoring piracy of their work.

They, along with Bette Midler and Elvis Costello among others, have signed a public complaint to the U.S. Copyright Office alleging that Google is profiting "off of stolen content."

These artists say Google and You Tube don't do enough to permanently remove pirated content from their searches, and are thus costing music professionals' money.

Their filing reads, "Many big tech companies have figured out how to game U.S. law - hiding behind its sweeping immunities while earning billions off of our work."

They also blame "dysfunctional" laws for allowing You Tube and other streaming video services to "swallow up almost every other form of listening, while paying among the lowest royalties in the business."
